Hi,
you are nearle there, only some small mkodificatioin needed:
First make an empt array: g={};
then append your graphics to this array:
numel=3;
y=0;
For[i=1,i<=numel,i++,
AppendTo[g,
Show[Graphics[{Hue[0.55],Rectangle[{0,y},{4,y+1.5}],RGBColor[1,1,1],
Rectangle[{0.2,y+0.2},{3.8,y+1.3}]}],AspectRatio\[Rule]Automatic,
ImageSize\[Rule]100]];y=y+2.5];
then combine the tthree plots into one:
g=Show[GraphicsArray[List/@ g]];
and export this:
Export["rectangles.bmp", g, ImageSize -> {150, 170}];
